About 0U9M0ZZ
0U9M0ZZ is the ICD-10-PCS code for a drainage procedure on the vulva using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to other incision of vulva and perineum, the ICD-9-CM procedure title it maps to (71.09).
For a different body part, codes include 0U900ZZ (right ovary), 0U910ZZ (left ovary), 0U920ZZ (bilateral ovaries), 0U940ZZ (uterine supporting structure), 0U950ZZ (right fallopian tube), 0U960ZZ (left fallopian tube) and 8 more.
The same procedure with a different approach is coded 0U9MXZZ (external).
With a different device, use 0U9M00Z (drainage device).
It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 746 (Vagina, Cervix and Vulva Procedures with CC/MCC) and DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Vagina, Cervix and Vulva Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
